Question

я нуб ie в kotlin но я сделал этот код для приложения: MainActivity:

enter code here

и maingame activity:

Answer 1

Я подозреваю, что в

actualnm = FileInputStream(amountofnm).bufferedReader().use {
        it.readText().toFloat()
}

вы получите что-то, что не может быть преобразовано в Float. (Я считаю, что пустой строки достаточно). Вы можете попробовать toFloatOrNull и обработать ноль каким-либо образом: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/to-float-or-null.html
